ADJUSTABLE SHOVEL-PLOUGH- fiit r fitlgrtnlt ttittfth to in flgest gutters earn tut mating and at flgt smut.

TO ALL WHOM IT MAY GONGERNZ Be it known that we, Tunnnnus DONELY and Josnrn B. CRES-SLER, of Southampton township, Fra klin county, and State of Pennsylvania, have invented a new and useful Improvement in Ploughs; and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, in which.-' Figure 1 is a side view, having one wheel removed.

Figure 2 is a plan view.

Figure 3 is a rear end view of shaft and axle.

Figure ii is a side view of main lever.

Figurefi' is a top view of one plougln Figure 6 is a side view of same.

Figure 7, several views of levers for operating the tongue. No. 1, end view of curved catch to sustain the end of tongue; No. 2, plan view of the same; No. 3, side view, showing the upper curve, fulcrum, and foot-lever. I

Our invention consists in the combination of a lever-adjustment to a series of ploughs, arranged under the axle of a pair of wheels, so that any one stock, of each set of ploughs, may be lifted at pleasure, or all may be lifted at the same time. Also in the manner of connecting-this lever to a tube or hollow cylinder, upon an independent shaft, which is connected to the main axle, so. that the driver, in his seat, may, by moving this lover transversely, in either direction, lead the gang of plou'ghs to the right or left, while the horses are continuing in the direct line, and this wan-extent equivalent to any practicable distance between the wheels; and at the same time, by a forward motion ofthe lever, can lift all the ploughs clear from the ground, and when desirable, can drop either the right or left plough only, or all at once, as the nature of the case may demand it. This is accomplished by the use of secondary levers, working upon and near the top of the main lever, and operating upon two pawls, which are placed in a slot in the'lowcr end of the main lever, which pawls catch hold of two rods, rigidly fixed to the tube or hollow cylinder, working around the shaft,'and on the ends of whichftub'cs are fixcd arms, extending backwards and downwards, and connected to the plough'stocks beneath, by straps on each side, made movable upon rivets at each end.

Our invention also provides for a-proper direction of the gang of ploughs, when it becomes necessary to carry them close to a fence, or any other object, when the team cannot draw the apparatus near enough to cultivate the ground. This is effected by another combination of levers, in such a manner that the driver, by hearing with his foot on a foot-lever, will detach from the end of the tongue a pawl, which-holds it to its place, when the course of the apparatus is direct. This being removed by pressing another lever opposite to his hand, either to the right or left, he will givc the wheels a direction at any angle required to bring the ploughs to the right or left, while the team can continucon the original direction; and when the necessity for this divergence shall have ceased, by reversing the motion of the lever, the tongue will resume its normal positionr andthe ploughs continue as before, I

We also combine with these devices and. the side ploughs a detachable central plough, for the purpose of checking the ground,'as well as to act as a cultivator.

This segment passes through the end of thqtongue T, at t, fig. 7', Nos. 2 and 3, and serves as a guide for the tongue, when operated upon by the lever T t is' a curved lever, bentin several directions, and having at the tongue T two raised surfaces, t t, and a square joggle, to lit the width of the tongue, and in which it rests, and is held firmly until it is required to move the tongue, when, by depressing the end, t the curved part if is lowered, and the-tongue can be moved-laterally, by the lever T acting on the horizontal lever T, which has one end fastened by a movable riut, or'i-vtlio top of the tongue T, No. 1, fig. 7, at t; .1." 11, lower end of pawls P I, into which the lower ends of reds R R are linked; v v, springs, fastened into pawls at V V, and passing through the slot in lever L, and which keep thepawls down, they being pivoted by a pin, 1).

Having described 'the several parts of these improvements,'we will explain the manner of operating the apparatus.- The driver being'seatcd, the main lever, L, is nearhis right'hand. The ploughs all being in place, the team, is started. Should it be'necessary to lift the ploughs, either one or all, the drivcr'can dose by carrying lever L forward, and by pressing upon the two small levers Zlhc can drop' the p'loughs'instantly, or if only one is required, by pressing the lover I, holding it.. He can also at the same time, or otherwise, cast his hand to the right or to the left, when the ploughs will be moved in the contrary direction, for any purpose which may he requisite. While thesetwo operations are in progress, if it should be essential to change the direction of the ploughs, he can presswitli' his foot upon the lever t release the tongue at t F, and with his lefthand upon lever T move the tongue on either side, while the team will continue its direction down the furrow.

Of course, it will be understood that these are all operations whichv can'be performed separately and independently of each other, when only one is required, or simultaneously if requisite, I

Having thus fully described our invention, what we claim as new and useful therein, and desire to secure by Letters Patent of the United States, is v I I 1. The combination of lever L with subordinate levers l1, and their attachments, pawls and springs, WA. operating upon the sleeves S S, substantially as described. l

2. The combination of lever L with sleeves S S and shaft 8, to move laterally, as substantially, described.

3. The arrangementof levers T" T, and t, in connection with the tongue, substantially as described.

4. The use of a central plough, F, detachably arranged, in connection with the side pl'oughs, substantially as described 5. The combination of lever L and its attachments, forming a combined lever, with vertical and horizontal motions, coincident when necessary andconvenicnt, together with the adjustable devices T T, and-t, all oper ating together, substantially and for the purposes specified.

In testimony whereof, we have signed our names to this specification in the presence of two subscribing witnesses,
